CVE-2026-11801 is an authorization bypass vulnerability in the WPAdverts – Classifieds Plugin for WordPress affecting all versions up to and including 2.3.2. The flaw is caused by insufficient verification that a requester is authorized to perform an action on a REST endpoint associated with classifieds type data. As a result, unauthenticated attackers can query the affected endpoint and retrieve internal site configuration information that should not be exposed without proper access control. Exposed data may include registered post types, labels, associated taxonomies, form schema metadata, contact options, and custom field meta keys.
